Vastoadductor Membrane Detail

membrana vastoadductoria detail

The vastoadductor membrane spans from vastus medialis to adductor magnus, forming the adductor canal roof and transmitting the femoral artery through its hiatus into the popliteal space.

Region: Thigh
Biomechanics

Function & Actions

Creates the adductor canal and contains the adductor hiatus through which the femoral artery becomes the popliteal artery — a key vascular surgical landmark.

Clinical Relevance

Clinical Notes

The hiatus marks the femoral-popliteal transition — the site of above-knee popliteal bypass anastomosis. Fibrous bands here produce popliteal artery entrapment in young athletes.

Pathology

Common Injuries & Conditions

Femoral to Popliteal Bypass at Adductor Hiatus

The adductor hiatus marks the transition from femoral to popliteal artery and is the reference for above-knee bypass anastomosis.

Adductor Hiatus Compression

Fibrous band at the hiatus compressing the femoral artery producing popliteal entrapment syndrome, managed by band release.
